DESCRIPTION
The INA128 and INA129 are low power, general purpose instrumentation
amplifiers offering excellent accuracy.
Their versatile 3-op amp design and small size make them ideal for a wide range of applications.
Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100).
A single external resistor sets any ga...
